This is a weird one, but I am not sure if I am missing something here. There used to be a location for the link to HTML files in content editor web parts. I cannot find the url now! I want to know which HTML file the web part is showing at the moment so I can modify it. It not under any of these: Appearance, Layout, Advanced.
